-     * ComputedStyle properties
-     *
-     * Each property stored in ComputedStyle is made up of fields. Fields have
-     * initial value functions, getters and setters. A field is preferably a
-     * basic data type or enum, but can be any type. A set of fields should be
-     * preceded by the property the field is stored for.
-     *
-     * Field method naming should be done like so:
-     *   // name-of-property
-     *   static int initialNameOfProperty();
-     *   int nameOfProperty() const;
-     *   void setNameOfProperty(int);
-     * If the property has multiple fields, add the field name to the end of the
-     * method name.
-     *
-     * Avoid nested types by splitting up fields where possible, e.g.:
-     *  int getBorderTopWidth();
-     *  int getBorderBottomWidth();
-     *  int getBorderLeftWidth();
-     *  int getBorderRightWidth();
